I'm not even talking about the first column as there is no such thing as a standard electric car, is it a Zoe or a Tesla model X?

Moreover, production needs energy and the carbon intensity should be mentioned (so we suppose that they used the same value). A battery produced at the Gigafactory is going to have a smaller carbon intensity as most of its power supply is solar... By the way this study is very pessimistic. For example if I take the efficiency of the Tesla Model 3 (16.4kWh/100km) for the whole 150'000km we get 12.3 metric tons of CO2 (500gCO2/kWh), far from the 19 tons of the figure.
